You have too many asterisks before argv. Use just one, like this:
def testB(shift,*argv):
    print "first argument is %s" %shift
    print "all other arguments are:",argv

testB('mails','Jen','Jen at att.com','Joe','Joe at aol.com')

Two asterisks signifies keyword arguments, like this:

def f(**c):
    for k,v in c.items():
         print k,v

f(a=1,b=2)
